: I've always undestand that if you do a commit (replication does it), a new : searcher is open, and you lose performance (queries per second) while the : caches are regenerated. I think i don't explain correctly my situation
not if you configure your caches with autowarming -- then solr will warm up the new caches (on the new index) while the old index still serves requests -- this is all manged for you by the SolrCore, no need for core swapping. -Hoss
